What's the best way to compress an flv
Whether its a free software or not. Also if the flv has gone through a compression process can it still have interactivty (hypervideo / hotspots), What kind of compression might one expect, i.e. a 100 mb flv - I want someone to say, YEAH u could get it down to 40mb but i have a suspition the answer is closer to 95mb.

Firstly let me qualify my comment about Interactivity -- perhaps jargon wasn't the correct term. What I meant was that it doesn't affect the quality or download times of the video. I really should have used a term like 'dressing'.
The size is the resolution. It's the display resolution. There's too much jargon (now I'm using it correctly) on the internet. Lets take a standard Internet resolution of 320 x 240 pixels. This expression is exaclty the same as an image of that resolution, only this represents the resolution of each frame. If you try to blow up and print an image of that quality it will look terribel. Same for the video. Just go to YouTube and click on 'Full Screen' and you'll see what I mean. It has to streeeeeeeeeeeetch those pixels to cover the full screen. So if you have more pixels -- you don't have to stretch them to cover a given screen.
NTSC DVD has a display resolution of 720 x 480 pixels -- that's why when you display that on a (not too big) screen it looks great. But if you start looking at DVD on the big screen monitors that are around today -- it doesn't look so good. Along comes HD, which is 1920 x 1080 pixels -- and you can display that on a giant screen and you don't have to streeeeeeeeetch the pixels.
The bitrate is also simple. Remember when we all had dial-up. It was only 56K. That meant you couldn't receive anything at more that 56 killobits per second -- and that's very slow. Like even YouTube, which is not the best quality in the world is around 200Kb/s.
Imagine trying to look a nice stream today on dial-up. It would be like trying to fill up a smimming pool via a drinking straw from a bucket. What would happen is the straw couldn't handle the inflow and it would drip -- interrupting the flow -- and that's why video's drop out when you don't have the transmission speed to receive them if they have been encoded at a high bitrate.
In fact the pros in this industry call any transmission bandwidth 'a pipe' because that's the best analogy.
If you want to do a crash course in resolution and bitrates and codecs, like I said, get yourself a free copy of SUPER, which can change most formats and parameters in a video. And just mess with it, and have a look at the results -- change the formats etc. It basically has three boxes at the top -- the container format, then the video that's inside that container or carrier, and then the audio.

Reduce the bit rate, does that mean the amount of information downloadable by the user at any one time, I'm not actually sure what it means, could you tell me. I use flash cs3
